Jesse Kuhnert updated TAPESTRY-1213:
------------------------------------
Fix Version/s: 4.2
> Meta annotation structure
> -------------------------
>
> Key: TAPESTRY-1213
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1213
> Project: Tapestry
> Issue Type: Improvement
> Affects Versions: 4.1.1
> Reporter: Ron Piterman
> Priority: Minor
> Fix For: 4.2
>
>
> I had posted to the dev list the same issue with in regard of the binding
> annotations, in regard of meta this is not so complicated, and has real
> advantages:
> I would like to propse:
> depracate @Meta
> create a
> annotation interface @Metas (
> @MetaValue[] value()
> )
> where @MetaValue is : String name(); String value()
> the use case:
> Meta names can be used as standalone constants.
> Meta values can be used as standalone constants.
> currently, one has to define two constants: one to inject the meta, one to
> set its value, which is "unclean":
> currently:
> META_ROLE="role";
> META_ROLE_USER="role=user"; or META_ROLE + "=user";
> and
> @Meta(META_ROLE_USER)
> @InjectMeta(META_ROLE)
> instead:
> META_ROLE_USER="user";
> @Metas( @MetaValue( name=META_ROLE, value=META_ROLE_USER ) )
> and
> @InjectMeta(... the same as above.
> Ofcouse, the benefit is not straight forward, until one works with constants
> from sources outside of the tapestry project.
> The meta values may be defined outside the tapestry application( in the
> backend) - and one can not use it in a straight forward manner. instead one
> has to define an extra constant with the equals sign. Though this is not very
> "tragic" it is not straightforward, and I consider it an ockwardty (english
> spelling :( ) of the framework.
